A/N Hiya, just want to say that this is my first fanfiction so please review lots as it will help me. Not sure how often updates will be...I tend to suffer from writers block. I know that some aspects of this story are similar to one written by BludgerBunny, but I began writing this before I had read that one, so no intentional stealing was done there I promise. I hope you enjoy!

Chapter 1: The Train

Skye leant back in her armchair at Baker Street, exhaling softly. How long it taken her to reach this moment? To settle down and stop being so…. She didn't know the word. But maybe it had begun at Hogwarts. No, it had started long before that. But it had started to get interesting at Hogwarts.

She dragged on her trunk onto the train, bumping Draco's as she did. "Watch it Potter" he grumbled at her. "Shut up Draco. This thing is heavy." "I know, I've got one too." She smiled and lugged the trunk into the first empty compartment they came across. She let it fall to the floor in the centre of the compartment, too lazy to lift in into the luggage racks, and Draco promptly fell over it. "Potter!" "Malfoy!" She retorted with a smile on her face. "Get your trunk out of the way." "Fine." And with a lazy flick of her wand and a murmured incantation, her trunk gracefully lifted itself onto the rack above her head. Malfoy did the same with his and flopped onto the seat opposite her with a scowl. "Cheer up Draco, stop being so moody." Skye teased. He was always cross with her, but she didn't really know why. She knew that Lucius and Narcissa had always hated her. But she had no idea why. Maybe she wouldn't have to go back to Malfoy Manor after this. She would be glad. Teasing Draco was the only thing she had been able to do for the first 11 years of her life. Maybe it would be more interesting at Hogwarts.

In another compartment, a boy named Neville was asking another first year girl called Hermione to help him look for his toad. Sandy-haired Seamus whispered to Dean "Why would you bring a toad? If I had one I'd try and lose it as soon as I could." Dean sniggered. Hermione, rolling her eyes, dragged Neville from the compartment and stormed off down the train with him. Dean and Seamus snickered again.

Draco was still scowling at her. She had had enough. He had never liked her that much and if she was honest, she had never really liked him either. Mutual dislike, that's the way to go, she thought, how ironic. "Draco, what have I done to make you scowl at me for the last 11 years? Am I really that annoying?" This caused the scowl to darken even more on his pale face. "Now you mention it, yes." "What? What have I done?" "As we're on our way to Hogwarts, I better had tell you." "Tell me what, exactly?" "What happened. The reason that you live with us is that Dumbledore considered it safest for one of you to live as a pure-blood. The reason that it was you and not Harry…." "Who on earth is Harry?" "Do you want to know or not? Stop interrupting. Harry is your twin brother. When you were babies, living in Godric's Hollow with your parents, a Wizard called….He Who Must Not Be Named…." "Why don't you want to say his name? Are you scared ickle Dracey-Wacey?" "Every witch and wizard are scared of the name. But I'll say that so you know, or you'll keep pestering me. It's Voldemort." "Hang on, doesn't that mean Flight of Death or something?" "I don't know. Now will you please stop asking me questions? Anyway, You-Know-Who attacked your family. He killed your parents and he tried to kill you and Harry. That scar on your head, that's from the attack. But He died or something. Harry was sent to live with your muggle relatives. You came to live with us. I don't know why."

"Okay. So is Harry somewhere on this train?" "Possibly. He might be a squib or something, or he might not have wanted to come." At that moment a timid knock fell on the compartment door. "Yes?" Skye asked. A round-faced boy poked his head into the compartment. "What, Longbottom." Snarled Draco. "How do you know him?" Inquired Skye. "All pure-bloods know each other, somehow or another. We met last year. All Longbottoms are fat and useless, and here is someone fat and useless. Therefore, he's a Longbottom." The round-faced boy flushed and stuttered "I…I…was just wondering if…you maybe had seen a…a toad anywhere. I've lost him, you see." The boy sniffed loudly. "No we haven't, now get out you snivelling idiot. You're a disgrace to your blood status." "Draco!" Skye was on her feet, wand pointed at Malfoy. All the anger and bullying she had put up with at his stinking house. She had had enough. "How dare you! You call him a snivelling idiot, and you're worse than him yourself. No way am I saying in this stupid compartment with you. I'm going to find my brother. He'll be a damn sight better company than you ever were. Goodbye Draco." And with that she tossed her red hair over her shoulder, shoved Longbottom out of the compartment and waved her wand at her trunk. She shot one last burning hazel-eyed glare at Draco and stormed out, slamming the compartment door behind her.

"What's your name?" "Neville. Neville Longbottom." "Well, I hope you find your toad. I'm going to find Harry." "Wait, are you Skye Potter?" She nodded, slightly confused. "Wow! You're so famous! And Harry Potter's here too? Wow!" And the round-faced boy trotted back to his compartment, grinning with excitement. "Okay, well, that was weird." Skye said to herself. She pulled open a compartment at random, and, upon seeing two ginger twins and another boy with them, asked "Excuse me, but have you seen Harry Potter anywhere?" "Yes." Replied one of the twins. "But you can't go and ogle him just because he's famous you know." "I wasn't planning to. I'm his twin sister. I thought it was about time I met him." "Skye Potter? Really? But….we just saw Harry….And he didn't mention having a sister." "That's because I don't think he knows about me yet. A little surprise, don't you think?" She replied, winking at the second twin. "Okay, well, he's in compartment 207, carriage 3. There's a sign somewhere. He'll be in there with a skinny ginger kid with dirt on his nose. That's our brother Ron Weasley. We're Fred and George Weasley, and this is our friend Lee Jordan." "Pleasure. Well, thanks, and I'll see you around." She left the compartment and went to go find carriage three.
